Description

Microsoft Stream is a video streaming service for Office 365/SharePoint users. The videos are behind a login wall, but once logged in the videos seem to be HLS content. Supplying the cookie ID and token seems to be enough to download the video contents, as seen in this project: https://github.com/snobu/destreamer
